We had air conditioning installed on my existing furnace, and couldn't be happier with the entire experience. Workers were professional, friendly, communicative, and punctual.

We recently purchased a home in Door county. The house had a new furnace and AC installed by Wulf in 2016. The previous owner never had them serviced because she didn’t use the home often in the last several years. I just called because our AC lines are icing up. Was told even though they installed the equipment they would still consider us a new customer and they are not accepting new customers at this time. I asked who else I could call and was told to “google it.”

Critical: Professionalism
Fireplace needed repair, be prepared to do battle with customer service if your not pleased with the work. Over the years I’ve recommended Wulf Brothers to neighbors and friends - no more.

We had Wulf Brothers install a very complicated heating and air conditioning system in our new high efficiency home. They did a great job on the installation. More importantly however there were a couple of things that required some adjustments after we moved into the home. They were very responsive to my calls and had an excellent technician come out quickly to make the adjustments. I would recommend them to anyone needing heating and air conditioning services.
